transoins are dipped intermediatetheir ends and this particular construction is provided in order to permit the positioning of 61); tileverbar 9 8 with respect to the socket 92,

as .will be apparent. a The tension members 66 are provided with wear plates 104 Vwhich. are adaptedl to contact ,with corresponding wear. plates 106 the canir mounted bybraclrets 108`secu`red to the tran.:

'frame and connected by means of wear plates 120 and 122 respectively. The side bearings 114 of car A are positioned within the bearings 112 offcargBv and said bearings are so arranged as tooverlap each other and to permit relative movement of the cars A and B vwithout contact between said side bearing's. Itwill be apparent that the bearings 11'4 are necessarilyy arranged within the bearings y112 in order that they `may contact with the bearings 64 as will ybe obvious.

Secured to the topchords 8 of the truck frame and to the center brace 11 is a wear plate 124 for the purpose of vtaking lateral impact vofthe entire bolster asseinbiy, it being vapparent due to the swing links 16, under certain conditions, the entire bolster asseinbly` will oscillate. `Extreme oscillation will cause impact of the assembly with the truck side frame whicliwill be taken by the wear plate 124. Y

The end of carA is provided with a casting 126 which is positioned between the center sill members 128 and said casting is apertured to receive a coupling pin 130 which extends through an opening in one end cfa drawbar 132. The draw-barv extends to the end of car B, Yas clearly shown in F 3, and the end ofvsaid drawbar is arranged between upper V and lower castings 134 and 136 respectively,securedbetwe'en the. center sill ineinbers 138 of car B, as clearly shown in Figs. 3 and 4. The end of the drawbar 132 which is extended betweenthe Castings 134 and 136 is provided with a ferruledaperture which takes a. spring indicated generally at 140. The cantilever bar 98 is of the construction shown and particularly described in my (lo-pending application iiled December 1, 1927, Serial No. 237,012'7 and only va brief description thereof is necessary. The r,bar comprises an attaching portion 142 whichis secured to the runderfi'aine of car B by suitablerivets 144 and is provided withan enlarged head portion 146 (see Fig. 1) which is reinforced and strengthened by means of the brace and webs 148. The upper'snrfaceof the cantilever bar incliidesthe attaching portion 142 and the head 146,y and the same isprovided with a weil 150 having a partition 152 therein dividing the well into two portions v as will be apparent from an inspection of Fig. 3. The spring 140 comprises two sections 154 and 156 reof the well 150 respectively. A vretainer plate 158 is provided which serves as a wedge and is inserted between the two sections of the spring; the upper end ot the retainer plate 158 is exposed, as shown clearly in Fig. 3, whereby to permit the end to be grasped and the retainer removed trom between thetwo sections 154 and 156. The opening formed in the top plate 110 of car B is normally closed by a cover 160. rI'he specific construction-just described results in an assembly in which the drawbar is normally caused to act upon the substantial center of the spring 140 thereby obtaining the greatest eiiiciency of the spring.

Figs. 5, 6 and 7 disclose a modified form of the invention, in which the truck is identical with the truck shown in the other figures. n In Fig. 5, the spring cap is designated generally at 162 and comprisesan elevated supporting portion 164 and a lower supporting portion 166; the spring cap being provided with reinforcing webs 168 and also with depending flanges 170 which engage over the spring band 172 to support the spring cap. rlhe bolster in this modification is of truss type and comprises the compression member 174 which is preferably a channel, the end thereof extending over the supporting portion 166 and being secured thereto by any suitable means such as rivets or the like. The bolster also comprises the tension members 176, the ends of which are arched as shown at 17 8 and rest upon correspondingly arched upper side `flanges 179 of the spring cap and extend downwardly adjacent the depending side flanges 180 of the spring cap and are secured to the ianges 180 by means of rivets 182 or the like. The supporting' portion 164 has secured thereto the socket member 184 within which is mounted the bearings 186 adapted to Contact with side bearings (not shown) secured to the car end with which the truck is associated. The supporting portion 166 is provided with a bearing plate 188 which seats upon the end ot the 4compression member 174 and is secured, with said end, to said supporting portion. The bearing plate 188 is recessed to pr vide seats for bearings 190.

The compression member 174 has secured thereto substantially midway between the ends al bearing plate 192 recessed to support roller bearings 194 which support a corresponding bearing plate 196 secured to the lower surface of a tie bar or spreader bar 198, the upper surtace of which supports a truck center bearing 200 tor the reception of a body center bearing (not shown) secured to a car end.

rIhe spreader bar ortie bar 198 is ot channel shape, as clearly shown in Figs. 6 and 7 and secured in the ends thereof by means of rivets 202 or the like is the attaching arm 204 ot a bearing member comprising the bearing plate .208 recessed to seat upon the before-mentioned bearings 190.

The bearing member 208 comprises, in addition to the bearing plate just described, a socket 210 which receives ay roller hearing 212 adapted to cooperate with a sidebearing attached to an overlapping car end and similar to the side bearings heretofore described and shown in Figs. 2 and 4.

The compression members 174 of the truss bolster have attached thereto a lower center bearing casting quite similar to the casting shown in Fig. 2, and indicated generally at 214, the same being provided with spaced rein lforcing webs 216 extending completely around the casting and merging with the upper flange 218 of the casting by which the casting is attached to the'compression members 174. The casting 214 is provided with depending webs 220 at its base and with side flanges 222 extending 'from the bottom 224 of the casting; the bottom 224 seating on` the tension members 176, and if desired, suitable rivets 226 may be employed to rigidly connect the tension members tothe castinr. The remainder of the structure of the casting and its bearings and the connection ofthe bearings with an adjacent car end is similar to the construction heretotore described with respect `to Figs. 1 to 4 inclusive, and no further description is deemed necessary.
